The son of a former British ambassador to El Salvador, Christopher Wenner was very well brought up and a bit stiff in front of the cameras. He seemed a bit out of place on the show, although his derring-do commended him to viewers and the production team.

After he left it was clear that his talents lay in serious journalism, a career that has seen Chris in far more danger than during his time on Blue Peter. In 1985 family and friends feared the worst when as a war correspondent he went missing in Beirut. Fortunately, he turned up safe and well after 18 days.

Later in 1998, whilst working for ITN as a journalist for Channel 4, Chris was brutally beaten by Serb civilians in a mass protest of over 150,000 Kosova Albanians. Luckily, Chris survived that ordeal too.

Chris returned to celebrate Blue Peter birthdays in 1983 and 1998 when he also took a cameo part in that year's Blue Peter panto, Back in Time For Christmas.

A father of two, he now splits his time between journalism and running his own production company.

Christopher Wenner also had a walk-on part in the Doctor Who story The Awakening (1984).
